According to this FAQ:
http://www.faqs.org/faqs/dec-faq/pdp8-models/section-2.html
...the PDP-8 was OEM'd to a company called Foxboro Corporation that
re-badged it as the PCP-88.
Has anyone ever seen a PCP-88? I would assume it is functionally and
physically equivalent to a DEC PDP-8?

Hmm... core and and a single-chip 12-bit microprocessor sounds pretty
unlikely.. Plus, I'm fairly sure Fabritek made its own computers at one
point in time, and I doubt they were clones of anything.. Then again, I
can't say I've ever found any actual info on them, either.

I think that's out of the question, since it's embedded deep in
another non-computer-related thing that hasn't been made since the
late 80's.
> This is why it's much more interesting to deal with OLD computers.
I agree, but my aim is to either re-program this thing, or replace
the embedded computer completely with something that does work in a
well documented way.
It will require interpreting some (simple, open/closed and possibly
some "timed pulse" kind of things) signals from other equipment,
interpreting the signals, and displaying the results on a pair of
matrix displays. One is possibly twenty-something by twenty-something,
the other 8 or so by maybe 64. Of course, I've also thought about
replacing the matrix screens with an LCD of higher resolution.
The thing is, I'd rather see about just writing new code for it,
but to do that, I need to figure out just what I'm looking at.
Another related question is, assuming that this were an embedded
ASIC from that era, what could I hope to find inside? Might it
have its own internal PROM to store the program? (In which case,
I'd need to find a replacement, or use a different chip...)

I've noticed that my MV3100's SCSI host ID's are set to 6 - I thought
this odd, as host ID's are usually 7. Are all MV3100's set to 6, or is
mine unique? Anyway, I thought since my PC's host ID is 7, I could
connect my SCSI tape drive to both systems. So I ran a cable from one
connector on the back to my PC, and a cable from the other connector to
my MV3100. I figure it's a properly terminated chain, as each host
controller is terminated (I know the PC is, I assume the MV3100 is).
It *seems* to work OK. But can anyone tell me for sure if this is
"legal"? I'm sure I'm looking for trouble if I try to use the same tape
drive from both systems at the same time, but as long as I don't do
that, is this an okay setup? It would sure beat changing cables every
time I want to move the tape drive from one system to the other.

I noticed that downloads of the ISO images for RT11 & RSX freeware from Tim
Shoppa's website are slowwwwwwwww.
I'm not sure if he has a really slow internet connection, or if he (or his
ISP) is throttling bandwidth (I suspect the latter). To provide for faster
downloads to anyone who wants it, I am copying the RT11 & RSX freeware ISO
cd images to www.classiccmp.org/PDP11
They should be up there sometime tomorrow morning, don't download them from
me before then or you're likely to get a partial image. And you can bet
you'll get more than 14kbps from my servers :)
Also, if you only want portions of the freeware CD's rather than the entire
ISO image, the entire contents are already at that URL in natural (non-ISO)
form to download individually.

I went by a surplus place today and found the remains of a DG Nova 4x that they'd already scrapped. Further searching revealed a 4x that they hadn't gotten to yet. I grabbed it, the floppy drives (8") from both units and the front panels from both and the CPU and a couple of other cards from the first unit. I did leave behind the hard drives (that may have been a mistake). Does anyone have info on these?

early interactive cable project.

20 meg harddrive combo mounted were the normal power supply goes. Also
inside was a AE TRANSWARP GS card, AE VULCAN controller card for the HD,
and a AE RAMKEEPER card with 2 Apple ram cards mounted to it. There was
a dryfit A200 ext battery Sonnenscheen with it also that works with the
Ram card? The cables, mouse, and keyboard also came with it and all or
$12.21. I will have to go down to the shop and get a monitor to test it
with.

At another thrift I got a Genesis 32X unit for $3.93, Actimate Arthur by
Microsoft, A new unopened package from Teledyne with a early Data
Processing Symbols Template.
There several other goodies but they are too new to list.
Can anyone tell me anything about this chip?
Again, it's a Motorola chip, which is marked "zc93124cp"
Might it be some kind of embedded CPU?
What does it do, and where do I find more information
about it?

When 400 is displayed, the led next to the power switch goes off, the

No playing with the reset button or smashing of keys on the keyboard or

I don't suppose you have access to a MicroVAX? I always do this under VMS,
and then FTP the data over to a UNIX system. Unfortuantly I'm not sure how
you can do this under RT-11, however, I'd guess that at a minimum you'd need
a RL02 drive and pack to hold the image for transfer over the the PC.

That can be disabled by the application. Disabling PrtSc

But if somehow they were able to do even that, a program

Since I've seen several people express this same sentiment,

it seems to work reasonably well.

Hello:
Can someone tell me or point me towards a site with
information on the power requirements for a HP C19
printing calculator?
I've got one which I'd like to sell, but I'd like to
see if it works or not first. It appears to be in
decent shape, tho the carrying case is getting ratty.
I see on the back it says "5V" and "1W", but the
connector (I assume for a AC adapter) isn't labeled,
and it has no power pack.
Thanks in advance,

Hehe, there goes the last VAX out of my workplace, and right into
my garage. And its a 6610! That means I will need to add in a few
processors, but there is my NVAX. Much work is before me. I should
get Ultrix 4.2 ported to it starting with the 6000-400 files. It
can't be so hard after the 6000-500 runs... We'll see. Does
anyone have the processor internal registers for the KA66A?
With some luck we can drop in just a very small set of kernel files
that can be reused under Ultrix 4.5 binary. For NetBSD it will be a
little harder to replicate all the missing stuff. I think I will want
to set up a fast cross compiling or native VAX box for that first.
That also means that a 6400 will become free on relatively short
notice. This one goes to Micheal McCabe, if he wants it (?) I am a
bit reluctant yet to convert the 6400 to a -600 so quickly after
I barely set it up. I guess I will take some time to actually do
the conversion. But in a matter of 4 weeks after I took her home,
I should probably get rid of that extraneous then 64x0 cabinet.
(the 'x' depends a little on how I will distribute all the CPUs.)
Also, there are the XMI and VAXBI backplanes (with some defect,
but certainly not everything on both of them) free for the taking.
They aren't claimed yet and that means I will decompose those
shortly.
cheers,
-Gunther

I was a slower learner. I sent of several times for the
items on the backs of cereal boxes. I can still remember
the propeller powered boat that when let loose would
dive into the water and sink. The baking powder powered sub did
work but was a lot smaller than the picture lead one
to believe. Anyway, I liked the sea monkeys.

Even then there should be a way IMO. There are a few programmes that allow
you to take a "screen shot", which means they produce a (.bmp .jpg...whatever)
file that shows what you had on your screen when you press some key. The one
I have was part of the Corel family...unfortunately, I haven't used it a
long time and I'm not home now to check its name. There could also be something
like this out as freeware, but I'm not sure on this.
Even if it's a bit complicated, this would at least allow you to print the
contents of those manuals the original viewer doesn't want you to. Legality of
such operations is another problem; I do not want to encourage illegal
actions. But I also don't want to see perfectly repairable appliances go to the
dumpster. Choose your way...

Ripping a phone book in half is really quite easy if you know the trick.
Just break the spine (it helps if the humidity is low, so the paper is less
flexible) first. Once the pages are torn at the spine, you can rip them the
rest of the way.

I just found a box of stuff that hasn't seen the light of day since my
company moved to our current building some 15 years ago.
In it was a Bulk Tape Eraser. The box pictures it being used on 5.25
floppies (as well as an 8 track tape and reel to reel tape). Is it safe
to use on floppy disks? I have a stack of HD 3.5's that I want to blank
out. Previously I just run them thru a computer to format them, but if a
bulk tape eraser can be used, it just saves me the trouble.
Also, how exactly are you supposed to use one? It has been as long since
I used one (probably this same one, used to use it to blank reel to reel
audio tapes). I thought I remembered that all you do is turn it on, hold
it over the item for a few seconds, wave it back and forth a bit, and
that was it. The item would be erased.
I just tried this one on a VHS video tape, it doesn't seem to do anything
to it. The picture is slightly distorted, but the tape is certainly not
blanked, not even close. I left it on for a good 30 to 45 seconds (the
label on the side of it says 1 minute on 20 minutes off, so I didn't want
to go beyond 1 minute).
It has a momentary switch on the handle, so it clearly isn't designed to
be left on very long. It makes a slight humm when on (and vibrates just a
touch, nothing visible, but you can feel it in your hand) so I assume it
is working. However, this is a Radio Shack brand item, so who knows if it
is doing what it should considering it is probably over 20 years old.
Any clues?

Hi,
I've just finished pulling an old Sierra Semiconductor FSK modem chipset
off an old modem board and I've hit a brick wall - I can't get any

their disti (Memec) don't have them...
The only site/company that does have them is FreeTradeZone
(www.freetradezone.com), but I don't fancy paying $10,000 per year for maybe
two or three datasheets a year.
BTW, the ICs are:
SC11011
SC11026
SC22201
Anyone got datasheets for these things lying around?
Finally, anyone know how to straighten pins on a QFP packaged IC without

Various terminal servers use RJ45 for serial
comms. One of the selling points of CAT5 was
that you wire your building once with CAT5 and
then can use the same wires for voice and data.
The data was usually either ethernet traffic
or serial comms (for printers and such). The
connectors were invariably (at least in my experince)
RJ45 for both ethernet and serial (and ISDN too).

I have some old DEC RL01 packs with PDP-11
diagnostic utilities - these are DEC originals:
AX-E380L-MC DLDP+DIAG#1 + DECX A1 SYSTEM A
AX-E441L-MC CZZLBLO DLDP+DIAG #2 + CPUTST + DECX B1 SYS B
They won't last forever, and I don't have any spare media
to back them up to, so I'd like to archive this software onto
my PC (for posterity - or perhaps to make available
to other hobbyists for use in the emulator, though I'm not
sure whether the Mentec license would cover this - it does say
"and associated utilities" however).
The question is, how can I get a copy of a pack as a
binary image onto the PC ? (to load in simh for example ?)
I have a working serial port, and I can run kermit OK on RT-11. However,
even if RT-11 will read the pack in DL1: (and I'm not
even sure of that), how can I persuade kermit
to take a copy of DL1: as an image ? I haven't found
a way of doing this. Simply doing "get DL1:"
doesn't seem to work.
Is there any kermit-like software out there that has
a PC client and can do a disk image transfer ?

The dd.SYS form of the driver is for the SB (formerly SJ) and FB
monitors (kernel, for unix weenies :-) The ddX.SYS form of the driver
is for the XM (XM, ZM, ZB) monitor(s). These last monitors are the ones
which have directives for controlling extended memory (anything beyond
64kb) and the drivers know how to get data from, and put data to, user
buffers in extended memory.

Sorry, I don't know the exact model number (it belongs to a friend
who got it from his dad). It hasn't been turned on in a long time --
what is the procedure for slowly bringing it up to make sure nothing
gets fried?
I imagine it would be to check the power supply and backplane wiring,
then the CPU card (including the voltage regulator), then memory
(including the voltage regulators), then other cards -- and the front
panel has to be checked at some point too. I could use more specifc
directions, a list of potential problems particular to the IMSAI, etc.
Thanks,

You can do it directly providing the controllers (and their hosts) are
well-behaved (which lets Windows off the hook). Back in the days when a
SCSI disk of any size cost nearly as much as the computer you might want to
attach it to, one enterprising company produced a system for the Acorn
Archimedes which allowed six Archimedes computers to share one SCSI disk
(and, I think, to "talk" to each other). I saw it working at an
exhibition, and I think it was made by Lingenuity. You might be able to
get more information from their sister comapany, Lindis:
http://www.lindis.co.uk, or from Jack Lillingston at Castle Technology:

Well.
I've been working on, and cleaning & testing, the weekend's finds. It
was a nice haul.
The aforementioned Macintosh System Software bundle, in shrinkwrap.
Way too much, but it's eBay Bait from hell. $6.99
An Atari 1040ST with SC1224 display and mouse - works great, no
burn-in, floppy reads & formats perfectly. $5.98
A Telex EB6 Dead Reckoning Computer. Telex still sells them, but I'm
sure this one's at least 15 years old.
Not a computer, but computerized, and the perfect ClassicCmp
Collector's accessory -- 1991 Ford F-150 with Straight-6 EFI and
overdrive manual transmission. It's on its 4th trip around the
odometer. 328,755 true miles. Doc's in love. Free. By the time it's
street legal I'll have $75 into it.

Anybody had luck hooking a VAXstation 4000/60 with "GS-2" (?)
graphics adapter up to a VRE01 flatpanel?
I finally got the VS4K from Doc today (thanks for dropping it off,
BTW, hope that mono video cable works for you), and got around to
hooking it up to the VRE a bit ago. However, all is not right - there
looks to be a scan rate/resolution mismatch, and I cant find ANY
dipswitches, etc, to set..
Suggestions? Links to the 4000/60 owners manual possibly?
I've got pictures of the results:
http://gallery.mrbill.net/view_album.php?set_albumName=vre01&page=2
Any help appreciated. I'd LOVE to get this display working..
(and the pictures show the display as yellow - its actually orange..)

Last year, I acquired an RK05 drive along with a number of
very old RK05 packs with RT-11 files. Since these distribution
are all older than V5.03, they are covered under the Mentec
license which allows usage under the SIMH emulator.
Last week, I was able to borrow an RKV11D Qbus controller
and copy most of the 17 packs (there were a few packs with bad
blocks) with the RT-11 files to a CD. Within a few months, it
should be possible to make these distributions available under
the emulator license, just as V5.03 and V4.00 or RT-11 are now.
In addition, while I still have the loan of the RKV11D, if there
are any users with RK05 media that wish to rescue the files, I
will be able to do so providing the media are still in readable
condition. If the RK05 media are in satisfactory condition and
I only need to read the files once for the COPY and a second
time for the verification (there are no bad blocks), then there
will only be a nominal charge for the destination CD or other
DEC media that I am able to use such as RL02 or TK50 or TK70.
If there are some "difficult" blocks that I am asked to try and
recover, then I will also charge for my time.
Sincerely yours,
Jerome Fine

Subject: An old VAX may need a new home...
Date: Thu, 20 Jun 2002 04:05:44 -0700
I few years back an old friend who I know longer have contact with gave me
an old MicroVAX and additional storage unit. I found your site just before
heading to bed so may pick this conversation up later and provide more
details.
The system stopped booting but I think it was a minor problem so tried to
repair it myself. However just at that time I found I had to move house so
the machine has been sitting in my second bedroom for 2 years collecting
dust with some parts not attached.
I'm moving house in 1-3 months time and won't have room for a lot of my old
equipment, so if I cannot use it I'll either give it away or throw it out
(however this VAX is very heavy so maybe I won't be throwing it as such
<grin>). I may also have a couple of manuals somewhere too.
I'm in Erskineville, Sydney, Australia - so if you know someone who either
can help me get it running again and/or wants it, let me know.
As I said, I'm heading to bed now, I'll provide more useful details in the
morning.
Regards,
Scott Bragg

PDF files can be marked to prevent printing, although
I think it's down to the software to honour this.
Limiting the number of viewings seems a little
daft - I doubt that anyone does this!

OK, now that I've exposed myself as an inveterate non-gamer.
If I have RF output (VHF Channel 2 or 3), can I run a composite

As for who's following up, I would say just send an e-mail to Jon
himself, and see what has not been spoken for. I'm not sure if they're
looking to get money for the stuff or not. I only know that the stuff is
avaiable.
If I had the space (and time), I would drive right on down there

Between this list, and the guys over at NetBSD/Vax, I bet almost all

Hey, this reminds me of something I though of earlier. Would it be
possible (not necessarly legal) to use a copy of RT-11 'for SimH' on the
pro-3{5|8}0 ? Also, how would I go about getting data from an RX-50 from
the PRO into an image that SimH likes? I've got access to a DOS and Linux
box with a 5.25" HD drive that I've used to successfully make copies of
RX-50's with teledisk. Is there a readily availble program, or will I
have to go play with INT 13h on my DOS machine to try and copy things into
an image file?
Thanks

Replacing the starting capacitors in the RA81 disk fixed the spinup
problem. They are a cylinder about 2" in diameter and 4" long and located
behind and below the HDA. They take about 10 minutes to replace.

Well, the 3' x 5' Jolly Roger flag on my wall has slowed them down a
bit. :) Not to mention that my "office" is really in the back of the printer
room, I just used some 7' cabinets to form a wall, so my office is sort of
"hidden".

I have the NBS (National Bureau of Standards) Pascal
compiler for the PDP-11 if you want it. It is written
in Pascal except for the run-time library. It appears
to be part of a DECUS tape dated Fall 1980.

Has anyone successfully used non-DEC SCSI tape (cartridge) drives with
VMS? If so, what types have you been successful with? Travan? DAT? 8mm?
Which models?
I just hooked up an HP SureStore TR4, and it's recognized, the device is
an HP T4000s. But when I try to access it (INIT a tape, etc) I get a
"parity error". I don't have any Travan-4 tapes though, just Travan-5
tapes, so that's what I tried... Could that cause a parity error?

Glad you mentioned that -- don't hook up both cables at the same time or
strange things may happen.
Also, what tapes do you have? I'm working on completing the entire set as
produced by Timex Computer Corp. and might be interested.

Yes: Zebra Systems in NYC.
BUT I suggest you exercise caution when dealing with this firm, i.e., only
pay them with a charge card in case they "lose" your order or find they
can't provide the products as advertised. I've had a couple of
unsatisfactory dealings with them. Another gripe of mine is that in the
last three years or so they've bumped the price from $29.95 to $99.95.
If you do a search on eBay for "timex,sinclair" you'll often find Zebra
selling kits there, usually with a starting bid of $49, so you can save a
lot by going that route.
The kits themselves (I've built at least two or three) are great. They're
not exactly identical to the original retail versions (no original Sinclair
BASIC manual, Zebrafied assembly instructions instead of original) but they
work, and one advantage is that the RF modulator (if you care to use it --
I don't) is UHF instead of VHF and provides a much cleaner signal.

Humm... I have a few dead drives here... maybe I'll yank the boards, use
some small hinges, and make myself a note pad case (I've seen them for
sale before, but never with components on them)
But I think if I start making all my office desk items from used computer
parts, then the staff here will REALLY think I have gone insane... then
again, maybe that will be a good thing, they'll stay out of my office
(barricading the door and covering the floor with electronic junk hasn't
stopped them... it just makes them trip when trying to come near my desk)

Why is this ironically? Philips and Sony developed the CD standard
together, so it would be natural that the oldest writers are Philips
and Sony ones. Sadly I don't have one, they were incredibly expensive
in those days. I do have the CM-100 and CM-110, the earliest Philips
CD readers. Those were built like tanks and still work today.

Probably. I've certainly seen the plugs we use, in Germany (or at least,
in Austria). Have a look at http://www.farnell.com/datasheets/21296.pdf
and see if the picture matches. Or look up DIN45325/IEC169-2

We used to have 300-ohm twin feeder for VHF (about 86-106MHz) FM radio
antennae, but it's rare now. Mostly 75-ohm coax.

Hi folks,
A few years ago, I posted a webpage about Lisa/MacXL technical info: <http://www.cs.dartmouth.edu/~woz/>. I intend to add more stuff to it...someday. It's still up, but I noticed the other day that the Lisa software archive, hosted on a separate ftp server, was unreachable. I guess the sysadmin closed it down. However I snagged the files from a backup and moved them, temporarily, to my own machine (which has a semi-static IP, broadband). So, if anyone needs a copy of (de-serialized) Lisa Office System, LisaTest, MacWorks, etc. the disk images are now here: <http://66.177.162.74/lisa-files/>
The link on the website has been updated as well.
If any of you (Sellam?) had listed the ftp link separately, please update. I'll send another note when I have the new, permanent home for these files.
Thanks,

Running since 01/22/2002 without a crash
I have a floppy problem with a Lisa 2/10 (MacXL ?): After inserting a
disk, a dialog appears (MacWorks XL) stating that the disk isn't
formatted (it is). If I chose to eject the disk, the spindle motor
continues to rotate. This doesn't happen during all ejects - it's an
intermittent problem, but I have never been able to read from the
floppy. This is a 400K drive.
1) I have cleaned the stepper cam, the head, and the ejection path and
have lubricated various parts. The head travels properly and the
ejection motor is functional. Where should I proceed?
2) The front fascia doesn't align properly due to the front of the 400K
floppy protruding a few millimeters. The front will snap into place
properly on the left 'catch', but is bulging out on the right catch. I
can't see why this is so, as the drive case is flush with the chassis,
and there is no possibility of the floppy sitting too far forward due to
the recessed mounting screws. The floppy appears to be just too long
(?) Has anyone else seen this.
3) Mouse related: How is the mouse supposed to secure to the connector
on the motherboard? The mouse has the standard two thumbscrews, but the
motherboard is lacking the metal jacket that would normally contain two
nuts to recieve the connector screws - it's just the black plastic DB-9
connector. Something seems missing in this picture. Any clues?

Or, you can make a cable to run between the computer and the RAM pack. Or,
you can make supports for both so that each is stable. Or, you can adapt
or buy a full-size keyboard so that the vibration from typing doesn't
disturb the components.

Yeah, I sent you the schematic earlier. Hope it helped. If you run some
wires from the pcb to the empty forward part of the shell, and use an
in-line female RCA jack, everything fits nicely inside (except the jack)
and the wires connected to the RCA jack will easily pass through the shell
near the "earphone" jack.

Finding an appropriate cassette recorder can be a challenge, so I would
suggest that you don't hunt for one using tapes of unknown quality. First,
try SAVEing a one line program onto a good-quality (doesn't have to be
great, just good) new blank cassette. Then re-LOAD the program. Try
different volume levels. This is the only way to verify that the recorder
is suitable for both operations. Then try LOADing your other tapes.
Last time I had to hunt for a suitable cassette machine (four years or so
ago) I went through several, including a nice Sony, before I found that the
best match was a Radio Shack (can't believe I'm writing this) Optimus.
Cost about $40, but worth it if you plan on using the TS-1000 very often.

ROFL! Which site? The payroll program I wrote and used at Consolidated
Electronics was well over 960 lines so I had to use a 64KB pack.

The really amazing part to all this is that they apparently haven't had
a power failure in 18 years...
Not much to report here, nice turnout, and a few odd items worth noting
. . . . .
There was a Fluke something, that looked like some sort of terminal that
set up data acquisition on an IEE-488 buss. He had the complete unit
and software and docs. All I remember is that the CRT had a 2:1 aspect
ratio. I'm sure this will turn on some of you obscure stuff collectors.
Gateway had a nominal presence there, but nothing worth noting, just
some PC stuff.
I did pick up a Commodore MPS-801 printer . . . are ribbons still
available and for how much??? If I can't get any ribbons, I'll just
contribute it to someone who wants to give it a nice home and call the
dollar invested a loss.
I even found one (wished there were more) AUI to 10 base T transceiver.
Now I can check out my Amiga ethernet boards, if the Xcvr is okay . . .
. .
Two TRS80 Model 100's were there for $50, with books. I was tempted,
but I passed them by. I'm sure I'll kick myself later on.
One last mention, not in line with this topic, but I do have an original
DEC (quantum) 240 Meg HD for trade. I have a surplus of Quantum drives,
and I have used this one on my Amiga with no problems. If you want one
for your DEC contact me off-list and we'll work out a trade or something
interesting.

I'll ask one of the designers when he gets back from his hols :-)
Since I think it is a voltage regulator of some sort, I
suspect the answer is no. The only dead board I ever
knowingly found in the pile of cards that I inherited
back in the lab at DEC was a DHV11 and it had had that
very component knocked off.

I don't know of anyone trying any serious OCR - the technology
has leaped forward in recent years, but not to the point that it
"just works". Given that there are somewhere between 300 and
700 DEC manuals online (just an estimate) any OCR process
has to be more or less one button push (i.e. as effortless as
straight scanning can be).
> online. I must do the RSX11M+ v4.1 orange wall I have at some point...
If you can get Mentec to agree to having them made available
(ask about bits of RSX and RT-11 V5 while you are at it ...)
then let me know and I'll get the CDs online. I did ask but
I've not heard anything back.

Hit SEND a tad early on that other one!
Various DEC manuals describe various
DEC chips in their appendices. The DHV11
tech manual happens to cover all of the
above except the DC006. One copy lives
at http://www.spies.com/~aek/pdf/dec/qbus/
I have not read that chipkit manual, but the
DHV11 manual includes a schematic so you
get a free reference design.

NOTE: The following list was put together by an assistant who was
not very familiar with this type of technology. This is a
list of most of the small parts we still have in cabinets.
This list should be used as a reference. We still have a
number of schematics, user manuals, and other assorted
documentation that we need to make a list up to send out.
We also have a number of assorted electronic items we need
to make a list up. Also there are still some larger items
such as racks, processors, disks, etc, that need to be put
into a list and sent out. We will do so as soon as we can.

Well. I was roaming yesterday and found a very nice old Macy's dress
box. In it was a TS-1000 with the TS-1016 16k memory cartridge, manuals
cables, and around 10 tapes, including PIM apps & games. After
soldering a broken joint on the m/b [1], running to WallyWorld at 2:00am
for a 300ohm-to-75ohm converter, and finally figuring out that I needed
to turn the brightness all the way up on the TV, the little booger
works.
This is the first computer I've had that was in need of board-level
repair to start with, simple enough to ID the problem (and not too
densely populated), and common and cheap enough to "risk" non-essential
modifications. Texas Instruments trained me as a "Certified Solder
Sucker" or whatever in 1982, but I really haven't done any electronics
work since. I build cables, solder all the joints on auto work, and
stuff, but till last night had truly forgotten the joys of eutectic
solder. Also till last night, I had truly not realized how much worse
my eyesight has gotten....
The card-edge cartridge connector is worn nearly through the traces on
the m/b. If the computer is jostled much at all, it loses the RAM and
its little mind. Next mod will be to do some (cheesy, yes I know) wire
patching to the finger traces.
I joked last night about just going to the thrifts for a $5 B&W TV,
but my experience with tuning and brightness matches Jeff Hellige's
comments, and I may do exactly that if I keep this. What I'll more
likely do is try Glen Goodwin's idea and tap the composite signal off
the motherboard.
The major question concerns the program tapes. I tried hooking up to
my stereo, the only cassette player I have anymore, and at any volume,
it just blows the Timex away. The display goes to hell, it doesn't seem
to "read" the program, and the display stays scrambled even after the
cassette stops. The manual states that a "Hi-Fi" tape deck, as opposed
to a cheap battery-driven portable, may be the source of problems. Does
anybody have a suggestion or solution? My instinct is that my cheap
stereo does enough EQ (not optional) to "blur" the signal.
One of the websites I found last night quotes the promo for the 16k
cartridge - something like "With the addition of 16 kilobytes of memory,
the Timex Sinclair 1000 could conceivably store a program of 960 lines,
but of course. no programmer would ever need to..."
Doc
Hopefully the attachment is still attached... I also have the first two
lists, if there is any interest in them. 'Mail Jon if you're interested
*and able to pick up*. I don't think he would be able to ship anything.

That's actually a good thing.
If the disk is wiped to the point that it needs a format from the OS,
then I can toss the disks in a general use box, and not worry about which
OS they are used on (Mac or DOS/Windows). This way, they can be formatted
fresh for the given platform they are needed on (yes yes, the mac can
read PC disks just fine, but I prefer not to do that for Mac specific
uses)

Ok, I guess I have to black track the stack of VHS tapes I have then. No
biggie, I was just hoping to avoid running them thru a VCR for 2 hours.

Ok, not exactly the way I had been using it. I was just putting it on top
of the item, turning it on, rubbing it back and forth a bit, then turning
it off and removing. I'll change my ways.

Good to know as a "fact" although I had suspected something like this
anyway, so I wouldn't have done it. I also wouldn't have tried it on Zip
disks, or Syquest carts or other removable "non floppy" media for fear of
the same problem. I suspect it might be ok on Zip disks, but I know those
are treated more like a hard drive platter than a floppy disk, so I don't
consider it worth the risk.

I prefer to take them apart and make wind chimes from the platters.

Let's see, each woofer is 8 ohms, so I have each side wired in
parallel to their own 1/4" socket on the back, so they'll show 4 ohms. My
head has two speaker jacks, so I can have it see 2 8 ohm speakers, or wire
in a homemade adapter so it will see a 2 ohm load. I've been thinking about
wiring in some DPDT switches, so I can flip each side between 2 & 4 ohms.
Depending on how much you travel with those speakers, here's how I
would set up the boxes...
- 15" in a ported box, all by itself. It'll be heavy. Nice boom for the
bottom end.
- 4 x 12" in a sealed box. Good tight response, but still has the bottom.
This could be used by itself quite nicely.
- 8" (or two) in a sealed box with a good horn tweeter. This would go best
used with the 15" cabinet, and an appropriate crossover. Maybe your amp has
one built in*. It will also be good for practicing by yourself. Nice & tight
response, and great if you play some funk style too.
* My Peavey does have a built-in adjustable crossover, but it's
pre-amp level. I then have to amp each side after that. One would get looped
back into the Peavey, and the other to a second power amp...
And hopefully you know the make and model numbers for those woofers.
That will be required if you want to build the best boxes possible for them.
I picked up the 2 speaker design books from Radio Shack to help with
the box design. Blaupunkt also has a basic DOS program to help with box
design too. The RS books had some decent rough size info for speakers, so I
assumed some average-low specs for my 12s went I calculated the box size. I
know the box is a little small for them. you can kinda hear it. But I don't
have the test equipment needed to find the real specs for these drivers, yet
:)
I'm working on a spreadsheet that has all of the formulas built in,
to help design different boxes. I'm not sure if I have it finished yet or
not, though...

It seems like we get a lot of VMS questions here, which probably doesn't
really fall directly under the list rules. I'm guilty of it too. But
there's so much knowledge here, it's hard not to ask. If anyone can
point me in the direction of an active VMS mailing list, I'll ask my VMS
questions there instead. And if there's not one, I'd consider setting
one up if there happens to be any mailing list software that works with
Exchange Server 2000.

I've got my ARCHIVE Python (model 4326) DDS-2 drive connected to my
MV3100. It is connected to that machine only (I don't have it
dual-connected, as discussed in another message thread) and it's on my
2nd SCSI controller chain. When I first boot the system, the first
restore I do from tape I get this message:
$ backup mkb100:rob/save *.*
%MOUNT-I-MOUNTED, ROB mounted on _BOB$MKB100:
%BACKUP-E-READERRS, excessive error rate reading MKB100:[000000]ROB.;
-SYSTEM-F-CTRLERR, fatal controller error
%BACKUP-I-OPERSPEC
%BACKUP-I-OPERASSIST, operator assistance has been requested
I then get "fatal controller error" messages whenever I try to access
the drive, until I turn it off and back on. After the above erorr, the
device shows 102 errors in SHOW DEVICE. Once the drive is turned off and
back on, it works fine from then on, with no problems.
If I boot the system, then turn the drive off, and back on, I *still*
get this message for the first restore I do. Then I turn the drive off
and back on, and all is OK.
If the first operation I do after booting is a backup TO tape, it goes
fine with no problems. But then when I try to do a restore from tape, I
still get the above error.
I've updated the drive's firmware to what I believe to be the latest
(28388-XXX V5.AQ). Right now I have the drive in an external enclosure
to test it. I was going to mount it internally in the MV3100, but if I
have to power the drive down to make it work, then internal mounting is
not possible. Could it be a SCSI termination problem?
The drive works flawlessly on my PC.
Thanks,

Bob Shannon -
Could you expand on your comments about non-s-100? According to the
website, it has a 10 slot S-100 MB, and "The IMSAI SERIES TWO utilizes
the powerhouse Zilog Z8S180 microprocessor and provides a complete
system on an IEEE-696 compatible S-100 board"
I am somewhat interested in the machine, but not if there is NO chance
of using some of my other S-100 boards in it.

This is NOT the UCSD p-System filer, it's one belonging to
a derived version of it that Apple briefly used on the Apple II.
To give you a little context, this was version II of the p-System
(the Roman numerals denoted architecture versions).
The one released by SofTech Microsystems, on the IBM and the Sage
and many others, was version IV, and it was a major overhaul.
(Status of segments regularised, almost no limit on the number of
segments in a system, all units swappable, dynamic linking,
instruction set even more compact than before, procedural
parameters, conformant arrays, semaphores, processes, etc. etc.)
Including using 80 columns on the screens! (Actually you could
change that in SYSTEM.CONFIG if you needed to, as seems clearly
to have been done with this example).
The filer used full names in its menus when it had the screen
width to do so. Which was most or all of the time after those
very early screens, unless, as I say, you did something to
SYSTEM.CONFIG .
As for making DOS look good, it made it look dreadful.
I still remember the pain of migrating to Turbo Pascal, which
was the BEST that DOS had to offer. Tiny file names, NO file
typing (file extensions are NOT file types), terribly slow
floppies, file volumes WITHOUT NAMES (which continues to this day),
every program needing all its code linked into it statically,
hence several copies of the same code on the same floppy -- etc etc.
(DOS's only advantages: more flexible number of entries in a
directory, and borrowing a poor man's version of directory trees
from UNIX. The p-System only allowed 77 entries in a directory
-- that was from a time when the DEC PDP-11 was popular -- and
had only 1 level of "subdirectory", which was an actual subvolume
file, of fixed size. And DOS was to acquire networking, whereas
work on the p-System seems to have suspended before that could
happen.)
Oh, and the p-System had powerful wildcards, including use for
mass name changes. DOS's wildcards were always weaker, and buggy.
And I really did like being able to compile on a 68000 machine
and run the compiled code on an 8086. Much faster turnaround
time. (I once did a project where we were supposed to use the
then-Microsoft Pascal on XT's for compiling -- all in native code
of course. We stayed in UCSD Pascal and compiled within the
p-System because it was FASTER!)

I found two interesting items today.
One is a PET 2001-8. It has the regular keyboard. Inside was an
"expandaram" board that added additional RAM and some peripheral slots for
the PET. The cards plugged in looked a lot like Apple ][ cards in their
form factor but I assume this is some proprietary bus. Anyone have info
on this?
Also, found a little module that apparently plugs somewhere into an Atari
ST. It's called the Magic Sac+ and on it it says "Turns your Atari into a
Mac". Anyone ever use one of these? Where on the ST would this plug in
to? Or is it for the Mega ST perhaps?

It's not much help, but the first Z248 that we recieved had MS-DOS 3.x and
Windows 1.0x floppies included with it.
I've never seen a copy of Windows 2.x, however, oddly enough I recently
found a shrinkwrapped copy of Windows 1.0 in the trash!
On a vaguely interesting Windows 1.x note, the PC version of the game
"Balance of Power" included just enough of Windows 1.x to run the game! It
was the only use I ever had for Windows 1.x :^)

I'm selling a Sharp PC-5000 that is new in the box.
The Sharp PC-5000 was one of the first clam-shell portables circa 1983
(the GRiD Compass and the Gavilan were it's contemporaries, as well as
another one from Australia, called the DuMont or something).
This is an awesome piece for any collection, especially those who collect
portables and early laptops. They don't get earlier than this, and
certainly not new, in the box.

Granted, but the difference was well explained in posts by others.

The leads carrying the composite signal are bare, and exposed. A pair of
clip leads is all that's required to gain access to that signal.

Sure, but if he's having trouble finding a modern TV with a tuner that
"likes" the TS1000 (most modern TVs don't), then using clip leads to grab
the signal would at least verify functionality of the computer. Bearing in
mind that the TS1000 has been described as "common as cockroaches" (Sellam
Ismael) and "an educational toy" (Richard Erlacher), plus the fact that the
ZX81 was originally sold as a kit and zillions of them were assembled by
schoolchildren, I think my advice was reasonably appropriate.
Feeling grumpy today, Fred? ;>)
